摘要： A biopsy forceps tool (preferably for endoscopic use) in which microwave energy is used to coagulate bleeding after a biological tissue sample is collected between a pair of jaws. The pair of jaws define an enclosure that is isolated from the microwave energy itself and insulated from any thermal changes that occur due to application of the microwave energy. The tool comprises a pair of jaws connected to a coaxial cable, each of the pair of jaws comprising an electrically conductive shell, the jaw assembly being movable between a closed position in which the electrically conductive shells enclose an internal volume for holding a tissue sample and an open position in which the internal volume is exposed in order to receive the tissue sample. The electrically conductive shells form a Faraday cage around the internal volume when in the closed position.

摘要： A pulsed RF cut waveform profile for electrosurgery, in which each pulse is formed of a composite of different pulse portions. The pulse includes a controllable treatment portion whose duration can be truncated as necessary to ensure that the average power delivered by the pulse as a whole does not exceed a predetermined value. A limit for the average power delivered by the composite pulse (i.e. total energy delivered over the duration of the ON and OFF portions divided by the pulse duration) may be selectable by the operator. The ON portion may have multiple sub-portions, which have different purposes. Each pulse may be automatically controlled for pulse width in this manner, so that the RF signal effectively responds intelligently to conditions at the probe tip during treatment.

摘要： A method of controlling RF power delivered from a bipolar electrosurgical instrument into a biological tissue. The method comprises controlling the profile of a RF waveform by: setting a maximum voltage limit for a voltage applied across the bipolar electrosurgical instrument; calculating a tissue resistance, the calculating step including a correction for an impedance associated with the RF channel; determining an objective tissue current limit from the calculated tissue resistance and a predetermined power dissipation target; and dynamically adjusting the current limit based on the determined objective tissue current limit. This control method may ameliorate the impact of an increased cable length on the accuracy of control of RF waveforms delivered to the tip of the probe.

摘要： An isolating circuit for an electrosurgical resection system comprises a combining circuit (308) having a first input connectable to an RF channel (306), a second input connectable to a microwave channel (304), and an output in communication with the first and second inputs for conveying RF and microwave energy to a common signal pathway. A waveguide isolator (312) is connected to isolate the microwave energy from the RF energy. The waveguide isolator comprises a conductive input section that mates with a conductive output section to define a waveguide cavity within a volume enclosed by the input and output sections. A DC isolation barrier is arranged between the input and output sections. The combining circuit output includes a signal conductor and a ground conductor. A capacitive structure is provided between the ground conductor and the conductive input section to inhibit coupling of the RF energy and leakage of the microwave energy.
